Abstract

For accurate determination of particle masses accurate knowledge of the momentum scale of the detectors is crucial. The procedure used to calibrate the momentum scale of the LHCb spectrometer is described and illustrated using the performance obtained with an integrated luminosity of 1.6 fb⁻¹ collected during 2016 in pp running. The procedure uses large samples of J/ → ⁺⁻ and B⁺ → J/K⁺ decays and leads to a relative accuracy of 3 × 10⁻⁴ on the momentum scale.
